OPTICAL STORAGE USING MATERIALS COMPRISING CHROMOPHORE OLIGOMERS WHICH CAN UNDERGO CYCLOADDITION

摘要

The present invention relates a method for optical storage of informationusing materials comprising compound having at least two chromophores and alinkage connecting the chromophores. The optical storage method can beeffected by use of light having a wavelength of from 100-1600 nm. The compoundapplicable for the method are typically dimers based on a skeleton made ofpeptides or amino acids, or alternatively peptide nucleic acid (PNA). Thechromophores may thymine, N-(C1-6-alkyl)-thymine, anthracene, acridiziniumsalts, tetracene, etc.
